RECOIL PAD FOR GUNS.

Application filed May 21,

provements in the type of recoil pad which comprises a relatively hardbase plate for attachment to a gun stock and a relatively soft rubbercushion carried by the base plate,

such relativelv soft cushion being provided with a plura ity oftransverse air pockets open to the atmosphere at the lateral mar- L0gins of the. pad.

Among its objects, the present invention contemplates the provision of arecoil pad of the general'type mentioned, wherein the air pockets andthe webs and walls which define such air pockets are so conformed and.arranged as to insure a maximum neumatic cushioning efi'ect in a padwhic has extremely resilient rear vertical edges, the rear face of whichreadily accommodates itself to B0 fit the shoulder of a marksman, andwhich in operation delivers the cushioned force of recoil straight back"to the shoulder of the marksman.

Another object of the present invention is the provision of a pad of thegeneral type hereinbefore mentioned in which the relatively soft rubbercushion is provided with self-closing o eni-ngs for the insertion of thescrews where y the base plate of the pad is attached to the gun stock,these self-closing screw insertion o enings enabling me to dispense withthe c osure-plugs which heretofore have been necessary when the softrubber pad has been vulcanized or otherwise permanently secured toitsbase late prior to the attachment of the recoil pad to a gun. Otherfeatures, objects and advantages of the presentinvention will appear asthe following detailed description progresses.

walls, webs and air pockets of the rubber cushion are capable.

S milar. characters of reference refer to similar parts throughout theseveral views. In the drawing 10 represents a gun stock prov ded With aplane rear face 11 to which the improved pad of my invention is attachedby screws, as will be more fully hereinafter explained. I

The recoil pad comprises a relatively hard base plate 12, preferablyformed of hard rubber, and a cushion 13 which is referably formed of agood quality of soft ru her. The

base plate 12 and the cushion 13 constitute a unit. They are preferablyvulcanized to-' gether. It is practical, however, to cement the softrubber cushion to the base plate, if

desired. The rear surface of the cushion,

that is the surface which is intended to bear against-the shoulder ofthe marksman, may

be a plane surface, if desired,'but is refer- I ably somewhat convex,being curve from side to side as is clearly illustrated in Figures 3 and4. By reason of this convexity I am enabled without weakening thecushion to bring its rear vertical edges 14-14 very close to the'firstline or row of elongated air pockets presently to be mentioned, thisar-. rangement affording and insuring great flexibility at such rearlateral edges.

Formed in the cushion 13 are two lines or rows of transversely extendingair pockets 15-15 and 16-16, each of said air pockets being open at bothends to the atmosphere.

' It will be noted that each of said air pockets.

and that the pockets" is elongated vertically,

red ckets-1616 of-the with respect to the air desired, cylindrical otherline or row. I

air pockets 1'7-17 may be formed in the cushion adjacent the extremitiesof the first line or row of air pockets to afiord ater resiliency nearthe heel and toe of t e pad and to improve the general appearance of.

the pad.

The two rows of air 'ckets hereinbefore mentioned virtually dWldQ thecushion into three rather distinct though integral walls, namely therear walla, the intermediate wall or partition b and the a, the centralwall or partition bein nected-to the rear wall l1)? dd and to the frontw by similar hor front wallconhor zonta webs zontal webs ee, the webs ddbeing staggered with respect to the webs ee.

I have found from practical ex erience that it isvery desirable that arecoi pad of the general type to which no invention relates should beextremel resi ient at its rear vertical edges, and shou d be capable ofconforming itself laterally to bear smoothly and snugly against theshoulder of a marksman. It has been found that if a pad does not havevery resilient rear lateral-edges the shoulder of the marksman is veryapt to be bruised along the line of one or the other of these edges,depending upon whether the marksman is a right-hand or left-hand.shooter. Furthermore, very few marksmcn in bring- I ing a gun pad totheir shoulder place the same in exactly the theoretically correctpoagainst the shoulder of the marksman.

sition against the shoulder, or hold their gun at recisely thetheoretically correct angle wit respect to the shoulder. For thesereasons it is desirable that a gun pad be capable of conforming itselflaterally best toDfit us to the particular conformation and arrangementof the cushion walls, webs and air pockets hereinbefore explained therecoil pad of the present invention is characterized by extremelyflexible rear lateral edges, and is capable of conforming itselflaterally as herein ex lained.

- Under t e recoil of thegun the walls, webs and air pockets of the softrubber. cushion are distorted substantially as illustrated in Figure 6,this distortion serving, to reduce the cross sectional area of the airpockets and expelling air therefrom and thereby increasing thecushioning effect of the recoilpad by reason of the fact that much. ofthe energy of the recoil is absorbed by the frictional re- Sistancewhich the walls of the open air pockets exert upon the expelled air.

The pad of-my present invention is adapted to be secured to the gunstock by screws 18 which extend freely through apertures inthe baseplate 12. I prefer to locate small metal washers 19 adjacent the baseplate apertures 1 and concentrlc' therewith to receive the thrust of thescrews 18, the said washers being preferablyimbedded in vthei cushion13v at the time-it is molded or atleast before it -is vulcanized i orotherwise permanently .se-' cured to-the'base plate. Y Formed inthe-cushion -13 and extendin therethroughfrom front to rear are conicaopenings 20-20, eachof said. conical 0 ening's be ng coaxial withio'neof the base p ate aperturesaforesaid and having itssmall end i face ofthe.

Having thus illustrated and described the preferred embodiment of myinvention, what I'claim is new and desire to secure by Letters Patent ofUnited States is:

1. A recoil pad for a gun stock comprising a base plate, a soft rubbercushion carried by the base plate, two vertical rows of verticallyelongated open-ended transverse air pockets formed in said cushion, thepockets of one row being staggered with respect to the pockets of theotherrow, the ends of the rear row of pockets being located immedi-'ately adjacent to the lateral rear edges of the cushion, the rearsurface of the cushion be'- ing curved convexl from side to side.
